Sesame response to nitrogen management under contrasting water availabilities
文献摘要：
Sesame is mainly cultivated under traditional,low-input agro-systems.Recent breeding developments promoted the modernization and mechanization of sesame cultivation.However,only a few articles have been published concerning fertilization requirements for both modern and traditional agro-systems.In field trials at two locations,we determined the response of irrigated sesame to nitrogen(N).Three promising sesame lines were tested combining two irrigation levels with four N levels.At a high irrigation level,N had a significant effect on growth,branching,and consequently,seed yield exceeding two-ton ha-1.A high N doze was accompanied by a decrease in the photosynthetic rate and leaf water potential.The 513C confirmed lower stomatal conductance under high N treatments.Under deficit irrigation,the N level had a minor effect on the monitored parameters,indicating N fertilization was not efficient.Seed oil content was negatively correlated with seed N concentration.Our results question the necessity of N application when water is limited,as N fertilization promotes vigorous development that rapidly depletes soil water.Thus,water availability should be considered when developing an N management strategy.For high-yielding agro-systems,roughly 80-120 kg ha1 N is required for optimal yield,bearing in mind the negative association between seed-N and oil content.
